FactoryRegistry lists 45,092 facilities whose primary industry classification is one of the 41 industries above. This is a list by industry, not a list of makers: Census reports that establishments in these industries produced Machinery contract manufacturing services, performed using materials owned by others (i.e., the customer), in the shares shown above, and does not say which establishments. Where a plant’s own website or a federal registry names what that plant makes, it appears on the plant’s own page with the source named.

The U.S. Census Bureau recorded this product line in 41 US manufacturing industries in the 2022 Economic Census, as the most specific line those industries reported. At least 1,049 establishments reported producing it; the count for 4 of those industries was withheld.

These are counts of establishments by industry: the Economic Census publishes them as industry totals and never as a list of plants.

NAPCS collection code 2053615000. Source for the product line, the establishment counts and the shares: U.S. Census Bureau, 2022 Economic Census (ECNNAPCSIND2022). Federal source data is public domain. Facility records are compiled separately by FactoryRegistry and carry their own sources.
